Use of beef ultralente for basal insulin delivery: plasma insulin concentrations after chronic ultralente administration in patients with IDDM
RA Rizza, PC O'Brien and FJ Service
Ultralente has been used as the basal component of intensive insulin
therapy programs. To determine the degree to which a single daily
subcutaneous injection of beef ultralente provides stable basal insulin
concentrations, plasma free insulin concentrations were measured in six
insulin-dependent diabetic patients over a 40-h period. All short-acting
insulin was withheld during this interval. Each patient had been maintained
on a chronic ultralente based program before study. Little if any evidence
of a temporal peak in plasma insulin concentrations was observed. Although
considerable variation in plasma insulin concentrations was observed in one
individual, beef ultralente provided relatively stable plasma insulin
concentrations in the group as a whole. Beef ultralente appears to be a
reasonable insulin preparation to use as the basal component in an
intensive insulin therapy program.
